Specification of Letters Intent.

Application filed April 7, 1911. Serial No. 819,598.

ing to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

Thisinvention relates to improvements in window locks, and particularlyto bodily removable locks which may be applied and removed wheneverdesired.

The object in. view is the construction of a locking device formedsubstantially as a wedge and designed to be placed between the windowsash and window frame in such a manner as to lock the sash against anymovement which tends to open the same.

A further object of the invention is the arrangement of a wedge lockformed with an elongated body portion having-a stiffening member, a pairof points or claw members, and ears which are designed to be used inapplying and removing the device, the whole arrangement being such as topresent a stiff, strong structure designed to be wedgedbetween a windowsash and its retaining frame.

With these and other objects in view the invention comprises certainnovel constructions, combinations, and arrangement of parts as will behereinafter more fully described and claimed.

In the accompanying drawings: Figure 1 is a fragmentary perspective viewof a window showing the invention applied thereto. Fig. 2 is a rspectiveview of an embodiment of the invention. Fig.3 is a top plan 1. Fig. 4 isan edge view of the structure shown in Fig. 1. Fig. 5 is a sectionthrough Fig. 3 on line 55. Fig. 6 is a front view of the structure shownin Fig. 2.

vent any substantial upward movement'of the sash. The locking member 3is formed with a body portion 4 having a chamfercd or sharpened end fiwhich is designed to be forced in on the order of a wedge between thesash 1 and frame 2 when the device is in operation. The body ortion 4 isalso constructed with a presse out portion 6 which forms a wedgeor"bracing member for stiff- Patented Apr. 16,1912. I

ening the body portion and preventing any bending or mashm of the same.

The front of the ody portion 4 is divided, and is formed into hookmembers 7 and 8 having pointed ends 9 and 10 and offset portions 11 and12. When the device is in oporation the pointed ends 9 and'lO aredesigned to enter frame 2 a sufficient distance for the offset portions11 and 12 to press against the frame which will prevent any furthermovement. Arranged to project in an opposite direction to members 7 andS are cars 13 and 14 formed with apertures therein, said ears beingdesigned to be engaged by the hand in applying or removing the device.Of course, it will be evident that a cord or some instrument could becaused'to remove the ears in applying and The device may be sashregardless of the is, whether the same is; closed, partially open, orentirely 0 en. If the window is entirely closed the evice is grasped bythe cars 13 and 14 and the cord connected with sash 1 is tem orarilymoved slightly away from the win ow frame and the chamfered portion 5 ofbody 4 is forced down between the frame 2 and sash 1 .until the pointedends 9 and 10 begin to enter the frame. If any one attem ts to raise thewindow either from the insi e or outside when the device is in thisposition any movement of the window will only act on the device forcausing the pointed ends 9 and 10 to enter farther into frame 2, but,will not permit a substantial upward movement of the sash. This is alsotrue where the window is partially open, as it is readily evident thatthe device may be applied to the sash even when the-same is partiallyopen so as to prevent any' further opening thereof. Of course, thewindow ma belowered if partially open, but insuc an event the devicewill eight thereof, that remain in engagement with frame 2 and anysubsequent openin of the window will be limited by the locking member 3.

hat I claim is: e

A. window lock comprising a body portion formed substantiall flatthroughout, and beveled at one end or defining an entering point, andbent down centrally for defining a cord receiving groove and a c ntrallongitudinal bracing rib, a pointed end structure extending at an angleto the body portion and designed to cause the body portion to bepositioned at an angle when in operation, and means extending from thebody portion designed to be used when applying and removing the devioe.

In testimony whereof I affix my signature in presence of two Witnesses.
